Abstract
The magnetic feedback nulling technique in a fiber-optic magnetometer is analyzed both theoretically and experimentally. Results indicate that high nulling efficiency requires large closed loop gain, and large signal-to-noise ratio requires system bandwidth no larger than the signal bandwidth. Large linear dynamic range, freedom from magnetic hysteresis, and long term stability are achievable.
